Promise Forever with a Nintendo Promise Ring: "Intendo"
Designer Paul Michaels made a concept piece of a Nintendo-inspired promise ring called the “Intendo”. With a power cord band and shiny stones in place of buttons, it’s perfect for the romantic gamer.
This is special, because you give it to a gamer you Intendo marry. ;)
